Oct 13, 2025 by wbrum.org 98 views

Introduction

The Environmental Protection Agency (EPA) Most Probable Number (MPN) Calculator is a powerful tool developed by Avineon, Inc. to determine the concentration of microorganisms in water and other samples. This calculator is widely used in various industries, including environmental monitoring, public health, and research. In this article, we will delve into the features, benefits, and limitations of the EPA MPN Calculator, as well as provide a step-by-step guide on how to use it.

What is the EPA Most Probable Number Calculator?

The EPA MPN Calculator is a statistical tool that estimates the concentration of microorganisms in a sample based on the number of positive and negative results obtained from a series of dilutions. The calculator uses the Most Probable Number (MPN) method, which is a widely accepted and reliable method for estimating microbial concentrations. The MPN method involves serially diluting a sample and testing each dilution for the presence of microorganisms. The results are then used to estimate the concentration of microorganisms in the original sample.
